[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A semi-trailer with stable transportation includes a cab 1 and a cargo box 11. The inner wall of the cargo box 11 is welded with a reinforcing plate 2. The surface of the reinforcing plate 2 is provided with a groove 21. The inner side of the reinforcing plate 2 is slidably connected to a sliding plate 22 through the groove 21. A connecting rod 23 is fixedly connected to the surface of the sliding plate 22. A hook 24 is fixedly connected to the surface of the connecting rod 23. A nut 25 is sleeved on the outer surface of the connecting rod 23. The transportation operation of goods is realized through the connection between the cab 1 and the cargo box 11. The cab 1 and the cargo box 11 are existing products, and their principles are no different from those of existing products. They will not be described in detail here.

[0025] Furthermore, the reinforcing plate 2 is long and the sliding plate 22 is disc-shaped. The sliding plate 22 is slidably connected to the carriage 11 through the sliding groove 21 and the reinforcing plate 2. The reinforcing plate 2 is not continuous on the carriage 11 through the inner wall of the carriage 11. Under the action of the reinforcing plate 2, the overall strength of the carriage 11 can be strengthened without affecting the normal use of the carriage 11. With the connection between the reinforcing plate 2 and the sliding groove 21, and the sliding connection between the sliding plate 22 and the sliding groove 21, the operation of the hook 24 in the carriage 11 can be adjusted and limited.

[0026] Furthermore, the hook 24 acts on the inside of the carriage 11 through the connecting rod 23 and the sliding plate 22. The cross-section of the hook 24 is C-shaped. The nut 25 abuts against the surface of the reinforcing plate 2 through the connecting rod 23. Through the connection of the hook 24 and the connecting rod 23, and the connection of the connecting rod 23 and the sliding plate 22, the connection of the connecting rod 23 and the nut 25, the position of the hook 24 on the reinforcing plate 2 can be adjusted and supported, thereby improving the range and performance of the hook 24 in the carriage 11. Through the connection of the hook 24 and the rope, the cargo in the carriage 11 can be separated and bound, thereby improving its stability during transportation.

[0027] Furthermore, an installation groove 3 is provided on the inner wall of the carriage 11. A baffle 31 and a pressure plate 32 are movably connected inside the installation groove 3. A screw 33 is threaded onto the surface of the pressure plate 32, and a handle 34 is inserted into the surface of the pressure plate 32. A limiting groove 35 is provided on the inner wall of the installation groove 3. The connection between the installation groove 3 and the carriage 11 facilitates the storage of the baffle 31 and the pressure plate 32 on the carriage 11, and prevents the baffle 31 and the pressure plate 32 from affecting the normal loading of goods.

[0028] Furthermore, the rotational contact points of the baffle 31 and the pressure plate 32 are distributed at opposite ends of the mounting groove 3. The baffle 31 is fitted and rotated between the mounting groove 3 and the pressure plate 32 in a plate shape. Through the rotational connection between the baffle 31 and the mounting groove 3, the baffle 31 is supported and stored on the carriage 11 under the rotational connection between the pressure plate 32 and the mounting groove 3.

[0029] Furthermore, the screws 33 are arranged in two groups at one end of the pressure plate 32 near the handle 34. The screws 33 are in contact with the surface of the pressure plate 32 and the baffle 31. The baffle 31 is rotatably and slidably connected to the mounting groove 35 through the limiting groove 35. The handle 34 has a "C" shaped cross section. Through the connection between the pressure plate 32 and the handle 34, the pressure plate 32 can be pulled easily under the action of the handle 34, which in turn facilitates the rotation operation of the pressure plate 32 in the mounting groove 3. With the screws 33 and the pressure plate 32 threadedly connected, when the baffle 31 needs to support the goods, the baffle 31 is moved to the corresponding position through the action of the limiting groove 35. At this time, the screws 33 are rotated to make the screws 33 and the baffle 31 abut against each other, thus completing the support operation of the baffle 31.

[0030] Working principle: When binding goods, use a tool to rotate the nut 25, causing the connecting rod 23 and hook 24 to move on the reinforcing plate 2 via the slide plate 22 and the groove 21. When the hook 24 slides to the corresponding position, rotate the nut 25 in the opposite direction to fix the working position of the hook 24. At this time, the goods are separated and bound by the cooperation of the rope and the hook 24. Then, with the use of the baffle 31, the baffle 31 at the corresponding position is rotated. Under the action of the limiting groove 35, the working position of the baffle 31 in the mounting groove 3 is changed, so that it abuts against the goods. Then, use a tool to rotate the screw 33, so that the screw 33 and the surface of the baffle 31 abut against each other, further completing the reinforcement operation of the goods and improving the stability of the transportation process.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
